# M<>M Relay

### (Meshtastic <=> Matrix Relay)

A powerful and easy-to-use relay between Meshtastic devices and Matrix chat rooms, allowing seamless communication across platforms. This opens the door for bridging Meshtastic devices to [many other platforms](https://matrix.org/bridges/).

## Features

- Bidirectional message relay between Meshtastic devices and Matrix chat rooms, capable of supporting multiple meshnets
- Supports both serial and network connections for Meshtastic devices
- Custom keys are embedded in Matrix messages which are used when relaying messages between two or more meshnets.
- Truncates long messages to fit within Meshtastic's payload size
- SQLite database to store node information for improved functionality
- Customizable logging level for easy debugging
- Configurable through a simple YAML file
- Supports mapping multiple rooms and channels 1:1
- Relays messages to/from a MQTT broker, if configured in the Meshtastic firmware (*Note: Messages relayed via MQTT currently share the relay's `meshnet_name`*)


*We would love to support [Matrix E2EE rooms](https://github.com/geoffwhittington/meshtastic-matrix-relay/issues/33), but this is currently not implemented. If you are familiar with [matrix-nio](https://github.com/poljar/matrix-nio/), we would gladly accept a PR for this feature!*
